The European Peacock (Aglais io) is a colourful butterfly, found in Europe and temperate Asia as far east as Japan. Formerly classified as the only member of the genus Inachis (the name is derived from Greek mythology, meaning Io, the daughter of Inachus). It should not be confused or classified with the "American peacocks" in the genus Anartia; these are not close relatives of the Eurasian species.
